Summary based on the NamUs case record (MP16600) and 1 other source
In the summer of 2010, a young man named Constantino Borjas Calleja vanished under circumstances that remain a mystery. On July 25, 2010, the 24-year-old was last seen in the area of Sasabe, Arizona, a small community situated in Pima County near the U.S.-Mexico border. His disappearance that day marked the beginning of a long and painful period of uncertainty for his loved ones, as all communication with him ceased. The exact details of his last known moments are sparse, but it is understood that he was in the process of crossing the border when he went missing.

Constantino is described as a Hispanic male with black hair and black eyes. At the time of his disappearance, he stood approximately 5 feet 5 inches tall and weighed around 175 pounds. A notable and distinctive physical characteristic is a long scar on the back of his head. When he was last seen, he was wearing an orange shirt, blue jeans in a size 32, and brown boxer shorts, also size 32. For footwear, he had on white tennis shoes with a strap, in a size 7.5. He was also wearing a green cap. These details provide a snapshot of the young man at the moment he disappeared, a collection of facts that his family holds onto in the hopes of finding answers.

The case of Constantino Borjas Calleja was officially reported to the Pima County Medical Examiner's Office on November 9, 2010, several months after his last contact. This agency took the lead in the investigation, documenting the circumstances surrounding his disappearance. The fundamental fact of the case is that he was last seen while attempting to cross the border near Sasabe, a journey fraught with potential dangers. Over the years, his case has remained open, a silent testament to a life interrupted and a family left waiting. The lack of resolution has left a void, and the passage of time has only deepened the mystery of what happened to Constantino after he was last seen on that July day.
